**使用css来实现幻灯片的效果**

（1）自动轮播，鼠标移入停止播放，鼠标移出继续播放，但是不能设置按钮自动播放，不能点击一个点跳转到对应的图片

思路：切换图片就是像上面js那样的想法，有一个大的容器装着所有的图片，每次想要切换一张图片的时候就用translate来执行左移，但是每次左移之后，我们又不希望立马左移下面一张图片，所以保留一段时间给这张照片停留在那里，所以这个时候下一帧的动画的translate应该跟上一张一样。

            </div>
    
        </div>
    
        </body>
    
    </html>

但是这样写是没有办法再添加点击切换的（纯css的状况下）

提供一种不是轮播，但是点击可以切换的代码
